I've been obsessed by glow in the dark ever since I was a little girl. Once I even made my own glow in the dark polish by mixing glow in the dark glue and some clear polish from my mom to get my own GITD polish. And o, how did I loved my homemade polish. I wore it everywhere and showed it to everybody around.
